ADMT120404R-F56 WKP35S milling insert for steel and cast iron — Walter Tools

The ADMT120404R-F56 WKP35S is a precision milling insert engineered for efficient roughing and medium finishing in steel and cast-iron applications.

• Tiger·tec Silver coated carbide grade WKP35S
• 15° relief angle for stable cutting
• 0.4 mm corner radius for accurate profiles
• Parallelogram 85° shape, 12 mm size

Reliable cutting performance for steel and cast iron

The insert offers proven performance on both steel (P) and cast iron (K) workpieces thanks to the WKP35S coated carbide grade. The combination of substrate and the Tiger·tec Silver technology reduces flank wear and supports reproducible cutting conditions, which leads to higher process stability and predictable tool life. For production environments where cycle time and part quality must be consistent, this geometry and grade provide measurable improvements in chip formation and wear resistance, helping to maintain dimensional accuracy across batches.

Geometry that supports productivity and accuracy

With a relief angle of 15° and a Parallelogram 85° shape, the insert balances cutting strength and accessibility to narrow contours. The 0.4 mm corner radius is suited to generating accurate edges while minimising notch wear during interrupted cuts. These geometric choices reduce vibration and contribute to smoother surface finishes, which can decrease downstream rework. The integrated F56 chipbreaker is matched to the grade and geometry to promote predictable chip breaking in long and short-chipping materials.

Coating and substrate explained for clearer selection

The grade belongs to the Tiger·tec Silver series and uses a coated carbide substrate optimised for the thermal and abrasive demands of steel and cast iron machining. Coating technology enhances oxidation resistance and reduces friction at the cutting edge, which supports higher cutting parameters where appropriate. When selecting tooling, this means fewer index changes and improved cost-in-use compared with uncoated grades in similar operations; the result is an overall increase in machining throughput and less downtime for tool handling.

Practical application and handling guidance

The insert is supplied in the ADMT designation and fits toolholders compatible with parallelogram, negative-insert systems; its 12 mm characteristic size and 4 mm plate thickness translate into robust support in the pocket and reliable edge strength. For best results, pair the insert with appropriate clamping torque and a holder designed for ADMT geometry to maintain seat accuracy. Regular monitoring of edge condition and adherence to recommended feed and speed ranges will extend performance and reduce scrap rates in production runs.

FAQ

What materials is this insert suited to?
The ADMT120404R-F56 WKP35S is designed for steel (P) and cast iron (K) applications, offering tailored wear resistance and chip control for these groups.

What does the Tiger·tec Silver series provide?
The Tiger·tec Silver coating improves oxidation resistance and reduces friction at the cutting edge, enabling more stable performance and longer edge life on the WKP35S grade.

How does the 0.4 mm corner radius affect the cut?
A 0.4 mm radius balances edge strength and profile accuracy, helping to produce reliable surface finishes while resisting notch formation in interrupted cutting.

Is the insert compatible with standard ADMT toolholders?
The insert uses the ADMT geometry and is intended for holders compatible with parallelogram-shaped negative inserts; correct clamping and seat accuracy ensure optimal performance.

What role does the F56 chipbreaker play?
The F56 chipbreaker is engineered to assist controlled chip formation for the grade and geometry, improving evacuation and reducing the risk of chip-related interruptions.
